Hexahedral Solid Element with Rotational Degrees of Freedom Based on a Novel Trail-Correction Displacement Interpolation Scheme

Huang, Guanxin; Li, Hangxing; Lu, Yonghe; Yang, Zhijun; Chen, Xin

2024 Iranian Journal of Science and Technology Transactions of Mechanical Engineering

doi:10.1007/s40997-024-00763-0

To address the issue of incompatible nodal parameters between finite elements of different dimensions, this paper introduces a new interpolation formula, named “trial-correction” displacement interpolation, utilizing trilinear and cubic interpolations. This interpolation method is applied to...

Primary Resonance of Nonlinear Spinning Timoshenko Shaft Based on a Novel Third-order Approximation Model Derived from Geometrically Exact Nonlinear Model

Beiranvand, H.; Hosseini, S. A. A.

2024 Iranian Journal of Science and Technology Transactions of Mechanical Engineering

doi:10.1007/s40997-024-00760-3

In this paper, a set of generalized nonlinear equations of motion for spinning Timoshenko shafts is derived using the concept of a geometrically exact approach. In order to investigate the primary resonance of the shaft, the multiple scale method is applied to the discrete equations of motion. In...
